Abstract
A steering angle indicating system for a vehicle includes a plurality of rotational angle sensors arranged within a steering wheel of the vehicle, each thereof producing an electric signal indicative of a turn angle of the steering wheel, an indicating unit responsive to the turn angle signals from the rotational angle sensors to compute the turn direction and the turn angle of the steering wheel and to indicate a result of the computation, and a power supply circuit supplied with electric power from a load side of a horn switch prearranged within the steering wheel. The system prevents the occurrence of a collision caused by careless starting of the vehicle by the driver.
